John B. (Jack) Curcio, Robert (Bob) GrohmanJack Curcio became the President and CEO of Mack Trucks, a Fortune 100 company. Jack was born in Hazleton, in a duplex company house on East Chestnut Street. In the other half of the duplex lived a boy named Robert (Bob) Grohman. Bob grew up to become President and CEO of Levi Strauss, Inc. In fact, these two next-door neighbors were named to those positions in the same year, same month (July, 1980). Amazing!
